Sean McConnell at the Parish. McConnell’s self-titled Rounder Records debut, issued earlier this month, follows more than a decade of DIY releases. Early cuts on records by Texas country mainstays Randy Rogers and Wade Bowen helped lead the Boston-raised singer-songwriter toward greener pastures in Nashville, where major acts such as Tim McGraw and Rascal Flatts recorded his tunes. Under his own name, McConnell is more folk-pop than commercial country, but the instant appeal of his singing and his instinctive songwriting chops make him a can’t-miss talent. Expect to find him at venues much larger than the Parish soon. Dallas upstart Troy Cartwright opens. $13. 8 p.m. 214 E. Sixth St. theparishaustin.com. — P.B.
